Abstract

PURPOSE:To increase the economy and the maintenance ability of the device, by obtaining the signal frequency through a simple frequency dividing circuit, through the use of a frequency which is not a common multiple of 4kHz and the signal frequency for the oscillation frequency of a main oscillator. CONSTITUTION:The main oscillation frequency of a main oscillator 1 is selected as 4,096kHz, it is frequency-divided into 1/2<10> at a frequency division circuit 2 to obtain 4kHz. On the other hand, the main oscillation frequency is frequency-divided into 1/1064 at a frequency division circuit 3 to obtain 3.84962...kHz. The error to 3.85kHz is -0.375...Hz, and the main oscillation frequency is frequency-divided into 1/1071 to obtain 3.82446...kHz. The error this time is -0.536...Hz.
